To disable the programs or shortcuts in the preceding folders, you must hold down the SHIFT key until the desktop icons appear. Holding down the SHIFT key is a better alternative than temporarily deleting or moving programs and shortcuts because this procedure affects only the current user session. To use the SHIFT key to disable programs and shortcuts in startup folders 1. Log off the computer. 2. In the Welcome to Windows dialog box, press CTRL+ALT+DEL. 3. In the Log On to Windows dialog box, type your user name and password and then click OK. 4. Immediately hold down the SHIFT key. The mouse cursor changes shape from a plain pointer to a pointer with an hourglass. (It might do this several times.) 5. Continue to hold down the SHIFT key until the Windows XP Professional desktop icons appear and the mouse cursor stops changing shape.

Let s say you want to develop an application for a veterinary clinic. To cover the cats who come to your clinic, all you must do is create a Cat class that also inherits from the class Animal. Then each class (Cat or Dog) could override functionality from the Animal class as needed. For instance, for the Cat class, the Speak method would be meow instead of bark. This means that the Speak methods for Cat and Dog are specializations of the regular animal Speak method. Let s look at the Person class example again. This time, I ll also show an Employee class that derives from the Person class. The Employee class derives from the Person class by using a colon (:) followed by the Person element. The keyword override changes the implementation of the Display method.

Using Internet Explorer to Access Your Local and Network Files Internet Explorer is designed to be a Web browser, but remember that Internet Explorer is also integrated with the Windows XP operating system. This means that Internet Explorer can provide you with access to Web pages as well as to resources on your local computer. The idea is to integrate the Internet with your local computing experience, making both easier. As you are using Internet Explorer, keep these helpful ideas in mind: G You can store Web page URLs in your Favorites folder, and you can store any shortcut on your computer in your Favorites list as well. Just drag the shortcut to the Favorites button on the Internet Explorer toolbar. G Your most frequently accessed URLs, documents, files, folders, and so on can be stored on the Links toolbar for easy access. Just drag and drop them on the Links toolbar. If you don t see the Links toolbar, choose View, Toolbars, Links to display it. G You can access Web pages as well as drives, files, and folders using the Address bar. Just enter the URL for a Web or intranet page. To access a local or network resource, specify its Universal Naming Convention (UNC) name, which takes the form \\computername\drivename\foldername\filename. For example, to open a file named News.doc located in the Data folder on a shared network drive named Datadisk on a network computer named Sales, you would type the UNC as \\sales\datadisk\data\news.doc.

Use the Group Policy MMC snap-in to disable programs that run at startup. Before you use this snap-in, you must be familiar with Group Policy concepts, and you must understand how to view registry entries and change local Group Policy settings.

Part V:

For information about Group Policy and using the Group Policy snap-in, see 1, Planning Deployments; 5, Managing Desktops; and 17, Managing Authorization and Access Control, and see Group Policy in the Distributed Systems Guide of the Microsoft Windows 2000 Server Resource Kit. Also see Using Group Policy in Windows XP Professional Help and Support Center and the Change and Configuration Management Deployment Guide link on the Web Resources page at http://www.microsoft.com/windows/reskits /webresources. If you are uncertain which startup programs to disable, view the registry startup information that appears in certain registry subkeys. For information about viewing registry entries, see To open Registry Editor in Windows XP Professional Help and Support Center and Table 29-6, Table 29-7, and Table 29-8. Caution
